Siemens Halske versus Siemens Rohre

I am new to tubes and have heard that Siemens Halske tubes are much better than Siemens Rohre. I am wondering if this is true for 6DJ8 tubes. Often times on Ebay I see tubes advertised as Siemens Halske but the box in the picture will say Rohre on it. Should I completely eliminate any Rohre tubes from consideration? Thanks in advance for your input

Grant- how can you tell they are genuine? so far I can tell that dull grey getter supports are older than shiny, but what else. is there anything to the story I heard that no genuine CCas were made with gold pins? I have a quad of gold pin, dull gray tubes stamped Siemens CCa. Of course I also have a pair of 308s in a well known tube dealers box that are inked Siemens 7308, but the dull top of tube marking says 7308 made in USA.

Well, they are all gold pins, some with codes on the support, all with 4 seams on bottle, one in blue/yellow Siemens & Halske box (very clean printing), 5 others in white boxes. Unfortunately, I do not have any gear right now that uses the E88CC/6922 tube.

Thanks for the input. For example this current add on ebay, the fellow says that there are no date codes etched on glass or frame and they have 07347 made in Germany printed on the back. He feels that they are early sixties. Any opinion as to genuine early 60's
